4. Maintenance
5. Cautions
■ Offset
Adjust as below when fine adjustment is required or there is an error of the measuring device.
▷ Offset adjustment can be carried out regardless of float position.
■ Simulation Current Out
When the check of correct output (4~20mA) between M-100R and PLC required, test it as below.
▷ After 5 seconds, it will be returned to actual float sensing mode.
▷ It can be tested regardless of the wiring of the sensor.
▷ Without the disconnection of cable, current output can be checked using the Digital Multimeter between the M-
100R terminal port T and -.
▷ When wiring of power supply, +, - shall be wired correctly.
▷ Power source shall be between DC +17V~+40V.
▷ Wiring shall not be carried out when the power is on.
